Purespring Therapeutics Ltd. has raised £80 million (US$104.6 million) in a series B, putting it on course to be the first to take a gene therapy for a kidney disease into the clinic. The money enables the company to move the lead program, PS-002, for the treatment of IgA nephropathy to clinical proof of concept and advance programs in other complement-mediated kidney diseases, and in an undisclosed glomerular kidney disease.
